Question

PLEASE ANSWER ASAP!! it might be me just being stupid but I was given a question on sequences. I was given the sequence 2,8,14,20. ive been taught to use the dn + ( a - d) method. so the first number in the sequence is 2 so that's a and the difference is 6 so that's d. so it is 6n + ( 2 - 6) which is 6n - 4? that's what I got anyways. on my homework sheet it is telling me that n, the difference, is 4n?! really confused somebody please help :)

Answer 1

I think ur homework sheet is wrong the difference is definitely 6
